' TORCH msrninurnn-nnnn f f Application filed July 26,

the following is a full, clear, and exact description thereof.

' My invention is directed to the provision of means of providingcommunication betweenangularly disposed groups of passageways in adistributer head or other member, and my invention finds particularapplicationin connection with the distributer torch head of an ignitiondevice of the type shown in my co-pending application for patent filedllilar. 18, 1919. Serial No. 283,325, and adapt: ed for association witha gas stove to light any one of the plurality of burners by directingasingle torch flame toward the se lected burner, gas being supplied tothe distributing head through a plurality of tubes.

' It is primarily the object of my invento provide a method offorming'series of communicating angular passageways a member of thischaracter which, reduces to a minimum the number of drilling and othermachining operations necessary in forming the member, whereby to'procurea decided economy in manufacture and whereby to permit the provision ofan exceedingly simple and compact structure.

{It is more particularly the object of my invention to providean'arrangement where by various of the passageways sections of thedevice may be cast in the device.

With the above and other objects and advantages in view, which will beapparent as the description proceeds, my invention resides in the novelfeatures of construction, combination and arrangement of the parts ashereinafter described and defined by the appended claims.

In the accompanying drawings:

Figure 1 is an elevational view of the disassembled sections of a torchdistributor head embodying my invention.

sleeve is formed with sleeve, is disposed slightly the 1919. Serial No.313,461.

Fig. 4 is a longitudinal sectional view through the head. v I hFig. 5 isa diagrammatic laid out view of t e the head showing the relation of thegrooves cast therein.

Referring nowmore particularly to the I form the distributer head in twocast sections, a sleeve 10 and a relatively longer core cylinder llwhich may be provided witha longitudinal central passageway 12 tolighten the structure. A laterally extending boss 13 is formed on thelower portion of the sleeve, and the upper portion of the radiallyoutstanding lugs 14- for supporting a shield for the torch head. Aseries of passageways 15, 15, 15 and 15 are drilled through theboss l3and are open at the inner periphery of the sleeve, these passagewaysbeing arranged in quadrangular relation and being adapted at their outerends for communication'with supply tubes for the distributer head.

The cylindrical section is cast with a diameter slightly greater thanthe internal diameter of the sleeve'lO, and a series of spirallyextending grooves are cast in the peripheries of these sections, thesegrooves corresponding 1n numberto the number of drilled passagewayswhich may be varied to 'meet differing conditions of use for which thedevice is intended. One of the peripheral grooves has one end 16 adaptedfor communication with the sleeve passageway 15 when the core cylinderis inserted in the sleeve and this groove extendsspirally up Patented g.s, race.

end portion l6 adapted for communlcation 'wlth the sleeve passageway 15,said groove extending spirally downward and around groove end 16 andthenspirally upward'in a reverse direction, terminating in an insetportion 16 adjacent the portion 16". A third groove has one end portion16 adapted for communication with the sleeve passageway 15 and extendsspirally upward below the second named groove and terminates in an insetportion 17. The fourth groove has one end 16 adapted for Certainportions and 18 in a circumferential series about the upper peripheralportion of the core, and when the core is disposed within the sleevethese inset portions form the upper end of a series of inclosedpassageways which are in communication with the laterally extendingpas-c sageways 15, 15 etc., oi the sleeve boss of the grooves arewidened to provide draw faces a facilitating the formation otthemoldsections of the core. The core is provided with a series of boreslS, 18,18 and 1S drilled from its top to the inset groove portions 17*,17? etc,thus providing vertically extending ports at the top ofthe distributerhead in which may be set jet tips 19, as shown in Fig. i to direct torchflames selectively in any one of a plurality of direct-ions.

In carrying out my improved method of forming the distributor head thesleeve 11') and core cylinderll are cast in the shape described. Thebores 15*, 15?, etc., 18". etc, are then drilled in said sections andthe inner periphery of the sleeves and the peripheryot' the core arefinished to suchrelativediameters that the core will fit in the sleevewhen the sleeve ras been expanded by heating- The sleeve isthen heated,and the core inserted therein with its grooves in proper coincidencewith the inner ends of the sleeve bore and the sleeve is permitted tocool whereby it shrinks on the core, thus connecting the sections in apractical integral block and closing the cast-in grooves of the coresothat a series of closed angular passageways are formed in thedistributer head having their terminal portions disposed in rightangular groups. By my improved method, the only machining operationsnecessary in the formation of the passageways consist in finishing themeeting peripheral-faces of the sections and in drilling the bores 15,15mm, and 18, 18" etc. and" an exceedingly simple and compact structureis procured.

lVhile I have shown'and describeda preferred embodiment of: my inventionit will be appreciated that various changes and modifications ofstructure and of operative grooves.

steps may be employed to meet differing conditions of use withoutdeparting in any manner from the spirit, of my invention.

What is claimed is: i

i 1. "A distributer member comprising a sleeve provided with a series ofapertures open at the inner periphery and a core cylinder secured in thesleeve and provided with grooves extending sprrally in its perlpheralsurface,

each ot'said grooves being closed by the sleeve and having one endportion in communication with a corresponding aperture of-the sleeve.

' 2. A distributer -1nember comprising a sleeve provided with a seriesof apertures open at the inner periphery of the sleeve and, acorecylinder secured in the sleeve and provided with grooves extendingspirally its peripheralsurface, eaeh'oi said grooves being closed by thesleeve. and having one end portion in communication with a correspondingaperturefof the sleeve, said core cylinder being provided withlongitudinally extending apertures in communicaof the sleeve tion withthe other end portions of the V distributor member comprising a a groupof I apertures 3. sleeve provlded with o 3611 at its inner 'eri her .acore 0 linder secured in the sleeve and provided with a peripheralgroove communicating at one end with one of the sleeve apertures and eX-tending spirally therefrom said cylinder being also provided with asecond groove communicating with a. secondsleeve aperture and extendingspirally'toward the said endof the first named around said end of thegroove and extended spirally in a reverse direction.

at. A distributer member comprising a sleeve provided with a series ofapertures opening at the inner periphery of the sleeve, and a corecylinder secured in the sleeve and provided with grooves extending inits peripheral surface, each of said grooves being closed by the sleeveand having one end groove and then portion in communication withcorresponding aperture of the sleeve.

In testimony that I claim the foregoing l have hereunto set my handjatMilwaukee, in the county of Milwaukee and State of Wisconsin.
